Modeling flow-based electrophoretic deposition for functionally graded materials
Miguel A. Salazar de Troya,Jason R. Morales,Brian Giera,Andrew J. Pascall,Marcus A. Worsley,Richard L. Landingham,Wyatt L. Du Frane,Joshua D. Kuntz +7 more
TL;DR: In this paper, a multiphysics model is developed that describes the spatial-temporal colloidal transport of particles in the suspension and reveals that suspension flow rate is the key factor influencing deposit morphologies observed in the experiment.

Generative Design for Performance Enhancement, Weight Reduction, and its Industrial Implications
TL;DR: This paper investigates the generative designing of a bracket that aids in the rotation of a linkage mounted on it with a revolute joint and finds the generated design considering various parameters is the best finish for performance enhancement and weight reduction.

Optimization Design of Lattice Structures in Internal Cooling Channel of Turbine Blade
TL;DR: In this article, an integral optimization method of lattice cooling structure, used at the trailing edge of turbine blades, concerned with heat transfer and mechanical performance, was presented, and the accuracy of the optimal LS was proved by experiment and numerical simulation.

Consideration of additive manufacturing supports for post-processing by end milling: a hybrid analytical–numerical model and experimental validation
TL;DR: In this article, the authors proposed a model combining an analytical approach to determine the cutting forces with a finite element model (FEM) to predict the dynamical response of the workpiece-supports system.

Superior effects of hybrid laser shock peening and ultrasonic nanocrystalline surface modification on fatigue behavior of additive manufactured AlSi10Mg
Erfan Maleki,Sara Bagherifard,Okan Unal,Alireza Jam,Shuai Shao,Mario Guagliano,Nima Shamsaei +6 more
TL;DR: In this paper , both the individual and combined effects of post-processing methods, i.e., laser shock peening (LSP) and ultrasonic nanocrystalline surface modification (UNSM) with the same intensity of 10−12 A [0.001 in], were systematically investigated on mechanical properties and fatigue behavior of L-PBF AlSi10Mg specimens.

Fronts propagating with curvature-dependent speed: algorithms based on Hamilton-Jacobi formulations
Stanley Osher,James A. Sethian +1 more
TL;DR: The PSC algorithm as mentioned in this paper approximates the Hamilton-Jacobi equations with parabolic right-hand-sides by using techniques from the hyperbolic conservation laws, which can be used also for more general surface motion problems.

Generating optimal topologies in structural design using a homogenization method
Martin P. Bendsøe,Noboru Kikuchi +1 more
TL;DR: In this article, the authors present a methodology for optimal shape design based on homogenization, which is related to modern production techniques and consists of computing the optimal distribution in space of an anisotropic material that is constructed by introducing an infimum of periodically distributed small holes in a given homogeneous, i.i.
